Klass' apartment is big,clean and nice,located in a busy financial district.Each drawer has a note sticken on it telling you what is it inside.Klass is so considerate that she prepare everything you may need.When I have question asking her,she always respond quickly,even in midnight.The manager on 2 floor is warm-hearted and the guard on 1 floor is also nice.My Thailand trip become perfect because of experience in Klass'.
